I suppose that you just need /tabSpecifications.*?Specifications/ to match the string in this case.

Update:

Sorry, it's been a long time for me not writing PHP codes.

Something went wrong because dot matches all characters including spaces, but not \n, and we should use [\\s\\S] to match all the characters including \n or simply add sim to the regular expression. 

<!-- language: lang-php -->

<?php

function matchin($input, $start, $end){
    $in      = array('/');
    $out     = array('\/');
    $startCh = str_replace($in, $out, $start);
    $endCh   = str_replace($in, $out, $end);

    $pattern = '/(?<='.$startCh.').*?(?='.$endCh.')/sim';
    // or you can use 
    // $pattern = '/(?<='.$startCh.')[\\s\\S]*?(?='.$endCh.')/';

    preg_match_all($pattern, $input, $result);
    return array($result[0]);
}

?>
